What to do when the generator loses water? (For water-cooled units).

When the cooling water in the generator is interrupted, the emergency pump should be connected first.) If the emergency pump is started in time, it will have little impact on the operation of the unit. The cold water pump None cannot be coupled in time. After a delay of 30 seconds, in order to ensure the safety of the generator, the generator oil switch must be disconnected via the water cut-off protection and the unit load must be reduced to zero. For units with water cut-off protection that does not trigger the automatic main steam valve, after load shedding, attention should be paid to the turbine speed, the turbine should be kept in no-load operation, the relevant parameters must be adjusted, the cause of the water cutoff to the generator must be found and the generator must be promptly returned to operation with load.
